I dont agree with her at all, friends should be the ones that keep it real with you, not be one of those "yes-men" that agree with everything even when its bad. We are all human and we arent perfect, so having friends that can see when things arent right and try to guide you and help you and support you making the right descision even if you disagree with them at the monment, thats a good friend.
I know i have sometimes disagreed with a friend, and the friend was actually right and we became even better friends. A friend that says yes to everything is not a friend and that is not what a friend or a friendship is supposed to be. I certainly wont be friends with someone if i have to say yes and support it whith EVERYTHING even when i see its not good. There needs to be a balance, you support your friend when its good and when you see its not right you can talk to them about and explain why they shouldnt make that descision.
Britney got it all wrong.
